makropipetteihin

Makropipetteihin, sometimes referred to as macro-pipettes, are manual dispensing instruments used in laboratories for transferring relatively large volumes of liquids, typically ranging from 1 milliliter up to several hundred milliliters. Unlike their smaller counterparts, micro-pipettes, which are designed for precise measurements in the microliter range, makropipetteihin are more suited for bulk transfers where high accuracy is not the primary concern.

These pipettes operate on a simple principle of vacuum or air displacement. A larger volume is drawn into the pipette by squeezing a bulb or using a plunger mechanism and then expelled by the same action. They are often constructed from plastic materials, making them disposable and cost-effective for frequent use, which helps to prevent cross-contamination. Some makropipetteihin are reusable and made of glass, requiring a separate bulb or piston for operation and necessitating careful cleaning between uses.

The accuracy of makropipetteihin varies, and they are generally not calibrated to the same degree of precision as micro-pipettes. They are commonly used for tasks such as preparing stock solutions, dispensing reagents in large quantities, and transferring samples between larger containers in various scientific disciplines, including biology, chemistry, and medicine. The user must ensure the correct volume is aspirated by observing markings on the pipette body, if present, or by relying on volumetric flasks or graduated cylinders for more precise volume determination.
